SPRAY-NOZZLE.

To all whom it may concern:

Be it known that I, JAMES W. MoCoN- NELL, a citizen of the United'States, residing at Washington, District of Columbia, have invented a new and useful Improvement in Spray-Nozzles, of which the following is a specification.

This invention relates to a spray nozzle, and while applicable for a variety of purposes, it is especially adapted for use in spraying a liquid into the combustion or expansion chamber of a torpedo, and will be hereinafter described with relation to such application.

One of the objects of this invention is to provide an improved spray nozzle of such simple and practical form as to prevent clogging when in use thereby providing a more reliable and eflicient device. Another object is'to provide a spray nozzle adapted to discharge a fine spray in the general shape of a cone, having relatively few parts, which may be readily manufactured, assembled, and kept clean. 7

Other objects will be in part obvious from the annexed drawings, and inpart indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof; all as more'completely outlined herein.

7 To enable others skilled in the art so fully to comprehend the underlying features thereof that they, may embody the same by the numerous modifications in structure and relation contemplated by this invention,. drawings depicting a preferred form have,

been annexed as a part of this disclosure,

and in such drawings, like characters of reference denote corresponding parts through-i out all the views, of which 1 Figure 1 is a central longitudinal cross sectional view of the preferred form of my device, and Fig. 2 is an-end view of the cap.

The spray nozzle comprises three main interfitting coacting parts, namely, a hollow cylindrical body member 1, a cap 2 and a dispersing member The body member provides a strainer 4 in the form of a hollowcup, closed at itsinner end and provided with openings or perforations 5 adapted, to strain the liquid or fluid Specification of Letters Patent Patented'Mar. 4, 1919.

passing through such openings into the interior of the hollow body member. The forward end of the strainer is threaded, as at 6, and engages internal threads 7 on a 1101- with a head member 10 in which are dis-- posed diametrically opposite cylindrical pas-. sageways 11, forming ports. These ports are arranged substantially parallel to the 7 axis of the cap.

The dispersing member 3 is in the form of a screw, provided with a head having the usual kerf, or driving slot 13, and a conical under-surface 14, and has athreaded stem 15 which engages a threaded opening 16 in the head of cap 2. lVhen screwed into this opening, the under-surface 14 of the screw head is disposed directly in front of the passages 11, thereby to'provide a suitable dispersing means. 7

In operation, the liquid or fluid, forced through the nozzle under pressure, is first strained on passing through openings 5. It then passes through passageways 11 as jets and strikes the conical under-surface 14 of the head of the screw, whereupon it is thrown out as a spray of substantially coneshaped form.

It may thus be seen that my device provides a simple and practical structure, which may be readily assembledand disassembled,

that others can by applying current knowledge readily adapt it for various applications without omitting certain'features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generlc or specific aspects of this lnvention,

and the'refore such adaptations should and; are intended to be comprehended within the meaning and range of equivalency of the following claims. 7 I claim as follows; I p l. A spray nozzle for the combustion fiask of torpedoes, comprising a head member, a

flange formed integral with said head mem ber and defining With said head member a chamber open at oneend, said head member being provided With a plurality of passages communicating With said chamber and having their longitudinal axes parallel to the longitudinal axis of the head member and disposed so that the points of their peripheries at the greatestradial distance from the center of the head member is tangent to the innerperiphery of said chamber, and a dispersion member secured to said headmemher having dlspersion surfaces pro ectlng above said passages.

2. A spray nozzle for the combustion flask of torpedoes, comprising ahead member, a

' flange formed integral therewith and defining with said head member a chamber open Copies of this patent may be obtained for at one end, said head member being provided With a plurality of passages communicating the head member is tangent to the inner pe-' riphery of said chamber, and a dispersion member having dispersion surfaces, secured in said head member and arranged directly adjacent the discharge end of said passages whereby the air gap between the dispersion surfaces of said dispersion memberand the discharge end of said passages is reduced to a mlnlmum.
